Route Reference

ABSTRACT

A user input is received on a wireless device specifying a starting location. The position of the wireless device is tracked from the starting location in response to the user input. A user input is received on the wireless device specifying an ending location, and a route is generated from the tracking of the wireless device from the starting location to the ending location. A first reference is associated with the route, wherein the route is retrievable by a selection of the first reference.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Provisional Patent Application Ser. No. 60/946,771 filed Jun. 28, 2007, and entitled “ROUTE REFERENCE,” the contents of which are incorporated herein by reference.

BACKGROUND

This disclosure relates to navigation using a mobile device.

Navigation systems have historically provided little intelligence other than the ability to navigate from an origination point to a destination point. Some navigation systems include functionality for using traffic information in navigating from the origination point to the destination point. Other systems have also provided more than one route for a user based on an origination and destination point, and allowed the user to select one of the routes. However, these systems do not allow the users to interact with the routes nor change the routes in any way.

Thus, the navigation system adds little value outside of providing a map to the user. Such problems with navigation systems can undermine a user's desire to use the navigation system.

SUMMARY

Disclosed herein are systems and methods for generating a route. In one implementation, a user input is received on a wireless device specifying a starting location. The position of the wireless device is tracked from the starting location in response to the user input. A user input is received on the wireless device specifying an ending location, and a route is generated from the tracking of the wireless device from the starting location to the ending location. A first reference is associated with the route, wherein the route is retrievable by a selection of the first reference.

In another implementation, an input is received specifying a first location, and an input is received specifying a second location. A travel route is computed between the first and second locations. An edit is received associated with the travel route, and the travel route is edited on the wireless device in accordance with the edit.

In another implementation, a user input is received on a wireless device specifying a starting location. A user input is received on the wireless device specifying an ending location. One or more routes are generated from the starting location to the ending location. User input is received on the wireless device selecting one or the one or more routes. A first reference is associated with the selected route, wherein the selected route is retrievable by a selection of the first reference.

In another implementation, a system includes a location engine for a wireless device that produces information indicative of a plurality of locations. The system also includes a route engine that receives information indicative of a first location, tracks a position of the wireless device from the first location in response to the information, receives information indicative of a second location, generates a route from the first location to the second location in accordance with the tracking of the wireless device, receives information indicative of en edit, and edits the route by tracking the position of the wireless device to the second location, wherein the route is associated with a reference.

DETAILED DESCRIPTION

FIG. 1 is a block diagram of an example mobile device 100. The mobile device 100 can be, for example, a handheld computer, a personal digital assistant, a cellular telephone, a network appliance, a camera, a smart phone, an enhanced general packet radio service (EGPRS) mobile phone, a network base station, a media player, a navigation device, an email device, a game console, or a combination of any two or more of these data processing devices or other data processing devices.

Mobile Device Overview

In some implementations, the mobile device 100 includes a touch-sensitive display 102. The touch-sensitive display 102 can implement liquid crystal display (LCD) technology, light emitting polymer display (LPD) technology, or some other display technology. The touch-sensitive display 102 can be sensitive to haptic and/or tactile contact with a user.

In some implementations, the touch-sensitive display 102 can comprise a multi-touch-sensitive display 102. A multi-touch-sensitive display 102 can, for example, process multiple simultaneous touch points, including processing data related to the pressure, degree and/or position of each touch point. Such processing facilitates gestures and interactions with multiple fingers, chording, and other interactions. Other touch-sensitive display technologies can also be used, e.g., a display in which contact is made using a stylus or other pointing device. Some examples of multi-touch-sensitive display technology are described in U.S. Pat. Nos. 6,323,846, 6,570,557, 6,677,932, and U.S. Patent Publication 2002/0015024A1, each of which is incorporated by reference herein in its entirety.

In some implementations, the mobile device 100 can display one or more graphical user interfaces on the touch-sensitive display 102 for providing the user access to various system objects and for conveying information to the user. In some implementations, the graphical user interface can include one or more display objects 104, 106. In the example shown, the display objects 104, 106, are graphic representations of system objects. Some examples of system objects include device functions, applications, windows, files, alerts, events, or other identifiable system objects.

Exemplary Mobile Device Functionality

In some implementations, the mobile device 100 can implement multiple device functionalities, such as a telephony device, as indicated by a phone object 110; an e-mail device, as indicated by the e-mail object 112; a network data communication device, as indicated by the Web object 114; a Wi-Fi base station device (not shown); and a media processing device, as indicated by the media player object 116. In some implementations, particular display objects 104, e.g., the phone object 110, the e-mail object 112, the Web object 114, and the media player object 116, can be displayed in a menu bar 118. In some implementations, device functionalities can be accessed from a top-level graphical user interface, such as the graphical user interface illustrated in FIG. 1. Touching one of the objects 110, 112, 114 or 116 can, for example, invoke corresponding functionality.

In some implementations, the mobile device 100 can implement network distribution functionality. For example, the functionality can enable the user to take the mobile device 100 and its associated network while traveling. In particular, the mobile device 100 can extend Internet access (e.g., Wi-Fi) to other wireless devices in the vicinity. For example, mobile device 100 can be configured as a base station for one or more devices. As such, mobile device 100 can grant or deny network access to other wireless devices.

In some implementations, upon invocation of device functionality, the graphical user interface of the mobile device 100 changes, or is augmented or replaced with another user interface or user interface elements, to facilitate user access to particular functions associated with the corresponding device functionality. For example, in response to a user touching the phone object 110, the graphical user interface of the touch-sensitive display 102 may present display objects related to various phone functions; likewise, touching of the email object 112 may cause the graphical user interface to present display objects related to various e-mail functions; touching the Web object 114 may cause the graphical user interface to present display objects related to various Web-surfing functions; and touching the media player object 116 may cause the graphical user interface to present display objects related to various media processing functions.

In some implementations, the top-level graphical user interface environment or state of FIG. 1 can be restored by pressing a button 120 located near the bottom of the mobile device 100. In some implementations, each corresponding device functionality may have corresponding “home” display objects displayed on the touch-sensitive display 102, and the graphical user interface environment of FIG. 1 can be restored by pressing the “home” display object.

In some implementations, the top-level graphical user interface can include additional display objects 106, such as a short messaging service (SMS) object 130, a calendar object 132, a photos object 134, a camera object 136, a calculator object 138, a stocks object 140, a weather object 142, a maps object 144, a notes object 146, a clock object 148, an address book object 150, and a settings object 152. Touching the SMS display object 130 can, for example, invoke an SMS messaging environment and supporting functionality; likewise, each selection of a display object 132, 134, 136, 138, 140, 142, 144, 146, 148, 150 and 152 can invoke a corresponding object environment and functionality.

Additional and/or different display objects can also be displayed in the graphical user interface of FIG. 1. For example, if the device 100 is functioning as a base station for other devices, one or more “connection” objects may appear in the graphical user interface to indicate the connection. In some implementations, the display objects 106 can be configured by a user, e.g., a user may specify which display objects 106 are displayed, and/or may download additional applications or other software that provides other functionalities and corresponding display objects.

In some implementations, the mobile device 100 can include one or more input/output (I/O) devices and/or sensor devices. For example, a speaker 160 and a microphone 162 can be included to facilitate voice-enabled functionalities, such as phone and voice mail functions. In some implementations, a loud speaker 164 can be included to facilitate hands-free voice functionalities, such as speaker phone functions. An audio jack 166 can also be included for use of headphones and/or a microphone.

In some implementations, a proximity sensor 168 can be included to facilitate the detection of the user positioning the mobile device 100 proximate to the user's ear and, in response, to disengage the touch-sensitive display 102 to prevent accidental function invocations. In some implementations, the touch-sensitive display 102 can be turned off to conserve additional power when the mobile device 100 is proximate to the user's ear.

Other sensors can also be used. For example, in some implementations, an ambient light sensor 170 can be utilized to facilitate adjusting the brightness of the touch-sensitive display 102. In some implementations, an accelerometer 172 can be utilized to detect movement of the mobile device 100, as indicated by the directional arrow 174. Accordingly, display objects and/or media can be presented according to a detected orientation, e.g., portrait or landscape. In some implementations, the mobile device 100 may include circuitry and sensors for supporting a location determining capability, such as that provided by the global positioning system (GPS) or other positioning systems (e.g., systems using Wi-Fi access points, television signals, cellular grids, Uniform Resource Locators (URLs)). In some implementations, a positioning system (e.g., a GPS receiver) can be integrated into the mobile device 100 or provided as a separate device that can be coupled to the mobile device 100 through an interface (e.g., port device 190) to provide access to location-based services.

The mobile device 100 can also include a camera lens and sensor 180. In some implementations, the camera lens and sensor 180 can be located on the back surface of the mobile device 100. The camera can capture still images and/or video.

The mobile device 100 can also include one or more wireless communication subsystems, such as an 802.11b/g communication device 186, and/or a Bluetooth™ communication device 188. Other communication protocols can also be supported, including other 802.x communication protocols (e.g., WiMax, Wi-Fi, 3G), code division multiple access (CDMA), global system for mobile communications (GSM), Enhanced Data GSM Environment (EDGE), etc.

In some implementations, a port device 190, e.g., a Universal Serial Bus (USB) port, or a docking port, or some other wired port connection, can be included. The port device 190 can, for example, be utilized to establish a wired connection to other computing devices, such as other communication devices 100, network access devices, a personal computer, a printer, or other processing devices capable of receiving and/or transmitting data. In some implementations, the port device 190 allows the mobile device 100 to synchronize with a host device using one or more protocols, such as, for example, the TCP/IP, HTTP, UDP and any other known protocol. In some implementations, a TCP/IP over USB protocol can be used.

Network Operating Environment

FIG. 2 is a block diagram of an example network operating environment 200 for the mobile device 100 of FIG. 1. The mobile device 100 of FIG. 1 can, for example, communicate over one or more wired and/or wireless networks 210 in data communication. For example, a wireless network 212, e.g., a cellular network, can communicate with a wide area network (WAN) 214, such as the Internet, by use of a gateway 216. Likewise, an access point 218, such as an 802.11g wireless access point, can provide communication access to the wide area network 214. In some implementations, both voice and data communications can be established over the wireless network 212 and the access point 218. For example, the mobile device 100 a can place and receive phone calls (e.g., using VoIP protocols), send and receive e-mail messages (e.g., using POP3 protocol), and retrieve electronic documents and/or streams, such as web pages, photographs, and videos, over the wireless network 212, gateway 216, and wide area network 214 (e.g., using TCP/IP or UDP protocols). Likewise, the mobile device 100 b can place and receive phone calls, send and receive e-mail messages, and retrieve electronic documents over the access point 218 and the wide area network 214. In some implementations, the mobile device 100 can be physically connected to the access point 218 using one or more cables and the access point 218 can be a personal computer. In this configuration, the mobile device 100 can be referred to as a “tethered” device.

The mobile devices 100 a and 100 b can also establish communications by other means. For example, the wireless device 100 a can communicate with other wireless devices, e.g., other wireless devices 100, cell phones, etc., over the wireless network 212. Likewise, the mobile devices 100 a and 100 b can establish peer-to-peer communications 220, e.g., a personal area network, by use of one or more communication subsystems, such as the Bluetooth™ communication device 188 shown in FIG. 1. Other communication protocols and topologies can also be implemented.

The mobile device 100 can, for example, communicate with one or more services 230, 240, 250, and 260 and/or one or more content publishers 270 over the one or more wired and/or wireless networks 210. For example, a navigation service 230 can provide navigation information, e.g., map information, location information, route information, and other information, to the mobile device 100. In the example shown, a user of the mobile device 100 b has invoked a map functionality, e.g., by pressing the maps object 144 on the top-level graphical user interface shown in FIG. 1, and has requested and received a map for the location “1 Infinite Loop, Cupertino, Calif.”

A messaging service 240 can, for example, provide e-mail and/or other messaging services. A media service 250 can, for example, provide access to media files, such as song files, movie files, video clips, and other media data. One or more other services 260 can also be utilized by the mobile device 100.

The mobile device 100 can also access other data and content over the one or more wired and/or wireless networks 210. For example, content publishers, e.g., content publisher(s) 270, such as news sites, RSS feeds, web sites, blogs, social networking sites, developer networks, etc., can be accessed by the mobile device 100. Such access can be provided by invocation of a web browsing function or application (e.g., a browser) in response to a user touching the Web object 114.

Exemplary Mobile Device Architecture

FIG. 3 is a block diagram 300 of an example implementation of the mobile device 100 of FIG. 1. The mobile device 100 can include a memory interface 302, one or more data processors, image processors and/or central processing units 304, and a peripherals interface 306. The memory interface 302, the one or more processors 304 and/or the peripherals interface 306 can be separate components or can be integrated in one or more integrated circuits. The various components in the mobile device 100 can be coupled by one or more communication buses or signal lines.

Sensors, devices and subsystems can be coupled to the peripherals interface 306 to facilitate multiple functionalities. For example, a motion sensor 310, a light sensor 312, and a proximity sensor 314 can be coupled to the peripherals interface 306 to facilitate the orientation, lighting and proximity functions described with respect to FIG. 1. Other sensors 316 can also be connected to the peripherals interface 306, such as a positioning system (e.g., GPS receiver), a temperature sensor, a biometric sensor, or other sensing device, to facilitate related functionalities.

In some implementations, the mobile device can receive positioning information from a positioning system 318. The positioning system 318, in various implementations, can be located on the mobile device, or can be coupled to the mobile device (e.g., using a wired connection or a wireless connection). In some implementations, the positioning system 318 can include a global positioning system (GPS) receiver and a positioning engine operable to derive positioning information from received GPS satellite signals. In other implementations, the positioning system 318 can include a compass and an accelerometer, as well as a positioning engine operable to derive positioning information based on dead reckoning techniques. In still further implementations, the positioning system 318 can use wireless signals to determine location information associated with the mobile device. Other positioning systems are possible. In still other implementations, the user can enter a set of position coordinates (e.g., latitude, longitude) for the mobile device. For example, the position coordinates can be typed into the phone (e.g., using a virtual keyboard) or selected by touching a point on a map. Position coordinates can also be acquired from another device (e.g., a car navigation system) by syncing or linking with the other device.

A camera subsystem 320 and an optical sensor 322, e.g., a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor, can be utilized to facilitate camera functions, such as recording photographs and video clips.

Communication functions can be facilitated through one or more wireless communication subsystems 324, which can include radio frequency receivers and transmitters and/or optical (e.g., infrared) receivers and transmitters. The specific design and implementation of the communication subsystem 324 can depend on the communication network(s) over which the mobile device 100 is intended to operate. For example, a mobile device 100 may include communication subsystems 324 designed to operate over a GSM network, a GPRS network, an EDGE network, a Wi-Fi or WiMax network, and a Bluetooth™ network. In particular, the wireless communication subsystems 324 may include hosting protocols such that the device 100 may be configured as a base station for other wireless devices.

An audio subsystem 326 can be coupled to a speaker 328 and a microphone 330 to facilitate voice-enabled functions, such as voice recognition, voice replication, digital recording, and telephony functions.

The I/O subsystem 340 can include a touch screen controller 342 and/or other input controller(s) 344. The touch-screen controller 342 can be coupled to a touch screen 346. The touch screen 346 and touch screen controller 342 can, for example, detect contact and movement or break thereof using any of a plurality of touch sensitivity technologies, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with the touch screen 346.

The other input controller(s) 344 can be coupled to other input/control devices 348, such as one or more buttons, rocker switches, thumb-wheel, infrared port, USB port, and/or a pointer device such as a stylus. The one or more buttons (not shown) can include an up/down button for volume control of the speaker 328 and/or the microphone 330.

In one implementation, a pressing of the button for a first duration may disengage a lock of the touch screen 346; and a pressing of the button for a second duration that is longer than the first duration may turn power to the mobile device 100 on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen 346 can, for example, also be used to implement virtual or soft buttons and/or a keyboard.

In some implementations, the mobile device 100 can present recorded audio and/or video files, such as MP3, AAC, and MPEG files. In some implementations, the mobile device 100 can include the functionality of an MP3 player, such as an iPod™. The mobile device 100 may, therefore, include a 36-pin connector that is compatible with the iPod. Other input/output and control devices can also be used.

The memory interface 302 can be coupled to memory 350. The memory 350 can include high-speed random access memory and/or non-volatile memory, such as one or more magnetic disk storage devices, one or more optical storage devices, and/or flash memory (e.g., NAND, NOR). The memory 350 can store an operating system 352, such as Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks. The operating system 352 may include instructions for handling basic system services and for performing hardware dependent tasks. In some implementations, the operating system 352 can be a kernel (e.g., UNIX kernel).

The memory 350 may also store communication instructions 354 to facilitate communicating with one or more additional devices, one or more computers and/or one or more servers. The memory 350 may include graphical user interface instructions 356 to facilitate graphic user interface processing; sensor processing instructions 358 to facilitate sensor-related processing and functions; phone instructions 360 to facilitate phone-related processes and functions; electronic messaging instructions 362 to facilitate electronic-messaging related processes and functions; web browsing instructions 364 to facilitate web browsing-related processes and functions; media processing instructions 366 to facilitate media processing-related processes and functions; GPS/Navigation instructions 368 to facilitate GPS and navigation-related processes and instructions; camera instructions 370 to facilitate camera-related processes and functions; and/or other software instructions 372 to facilitate other processes and functions.

Each of the above identified instructions and applications can correspond to a set of instructions for performing one or more functions described above. These instructions need not be implemented as separate software programs, procedures or modules. The memory 350 can include additional instructions or fewer instructions. Furthermore, various functions of the mobile device 100 may be implemented in hardware and/or in software, including in one or more signal processing and/or application specific integrated circuits.

FIG. 4 is a block diagram illustrating example routing instructions to facilitate proving navigation guidance to a user. The routing instructions can include a route engine 410, a presentation engine 420, an editor engine 430, a map system 440, a user interface 450, and a positioning system 318. The routing instructions 372 can receive input specifying a starting location 460 and an ending location 462 can generate a route using the starting location 460 and ending location 462. The routing instructions 372 can, for example, associate a reference with the generated route to be used in, for example, storing and retrieving the generated route. In one implementation, the routing instructions 372 can edit a previously created route.

In one implementation, a user input can, for example, be received on a mobile device 100 specifying a starting location for a route. The input can, for example, be received on the user interface 450. The mobile device 100 can, for example, provide the route to a user of the mobile device 100. The starting location 460 can, for example, correspond to a geographic location that is used to generate a route, and can be input manually by a user of the mobile device 100 based on the starting location. The input can, for example, be received on the user interface 450. The user can, for example, input an address corresponding to the starting location 460. The address can, for example, include a street number, street name, city, state and zip code. In one implementation, the starting location 460 can be indicated by a landmark, e.g., an airport or airport code.

In one implementation, the route engine 410 can automatically derive the starting location information using the current location as the starting location 460. For example, the user of the mobile device 100 can decide to navigate to a particular location from a current location. The mobile device 100 can receive an indication as to whether automatically derive the starting location 460 information. The route engine 410 can derive starting information using the positioning system 318 when the indication is received to use the current location as the starting location 460.

In one implementation, the positioning system 318 can be a global positioning system (GPS) device. In other implementations, the positioning system 318 can be provided by an accelerometer and a compass using dead reckoning techniques. In such implementations, the positioning system can be reset by marking the device's presence at a known location (e.g., landmark, intersection, etc.). In still further implementations, the positioning system 318 can be provided by using wireless signal strength and one or more locations of known wireless signal sources to provide current location. Wireless signal sources can include access points and/or cellular towers. Other positioning systems are possible. For example, a user may be driving in a car with the mobile device 100 and decide to use the mobile device 100 to generate a route to a specific destination. The route engine 410 can automatically derive the starting location 460 of the mobile device 100 by the positioning system 318. The mobile device 100 can automatically derive the starting location 460 information in response to a user input.

In one implementation, the route engine 410 can track a position of the mobile device 100 from the starting location 460 in response to the user input. The position of the mobile device 100 can, for example, be tracked in conjunction with the positioning system 318. In various implementations, the positioning system 318 can be provided by a separate device coupled to the mobile device (e.g., mobile device 100 of FIG. 1). In other implementations, the positioning system 318 can be provided internal to the mobile device.

The route engine 410 can, for example, start tracking the position of the mobile device 100 until an indication is received to stop tracking. For example, as the user in the above example moves from the starting location 460, the route engine 410 tracks the position of the mobile device 100 until an indication is received to end tracking of the mobile device 100.

In one implementation, user input can be received on the mobile device 100 specifying an ending location 462. The route engine 410 can stop tracking the mobile device 100 upon receipt of the user input specifying the ending location 462. The ending location 462 can, for example, be input manually by the user of the mobile device 100. The mobile device 100 can, for example, receive an address corresponding to the ending location 462 in response to a user input. In one implementation, the ending location 462 can, for example, be automatically derived by the route engine 410. The mobile device 100 can receive the ending location 462 as the current location of the mobile device 100 in response to a user input. The route engine 410 can derive the ending location 462 using the current location and the positioning system 318.

A route can include route guidelines including streets distances, landmarks, etc. that were taken while navigating from the starting location 460 to the ending location 462. Based on the complexity of a route, the route can include many route guidelines. Route guidelines, in some implementations, can include a discrete length of road which comprises a route. The route can, for example, include navigating directions from the starting location 460 to the ending location 462.

The route engine 410 can provide the route tracked to a presentation engine 420. The presentation engine can, for example, communicate with a map system 440. In some implementations, the map system 440 can be provided, for example, by a navigation service (e.g., navigation service 230 of FIG. 2). In other implementations, the map system 440 can be provided by a map store residing on the mobile device (e.g., mobile device 100 of FIG. 1). The presentation engine 420 can use the map provided by the map system 440 to overlay the route information.

In other implementations, the route can be overlayed on a map provided by a local map information store. In some implementations, the map includes a number of road representations. The road representations, for example, can be overlayed by traffic information 464 associated with respective route progressions. Traffic information 464 can be indicated, for example, by color coding on or alongside road representations, pushpin messages associated with road representations, traffic animations associated with road representation, etc. The presentation of the route can enable a user of the mobile device to navigate from a current location to an ending location 462. For example, the route the user took from the starting location 460 to the ending location 462 can be saved by the route engine 410 and displayed on the presentation engine 420.

In some implementations, the one or more routes can be generated based upon user preferences retrieved from a data store in conjunction with the user specified starting locations 460 and ending locations 462. User preference information 466, for example, might indicate a user preference for types of roads, distance, traffic, traffic control devices (e.g., traffic lights, stop signs, rotaries, etc.), time, preferred routes, neighborhoods, etc.

In one implementation, the route engine 410 can generate one or more routes based upon traffic information 464. The traffic information 464 can be retrieved, for example, from a traffic information 464 service. In some implementations, the traffic information 464 service can be provided by a government or commercial service provider.

In one implementation any of the generated routes can be selected as the route to navigate. The route engine 410 can, for example, provide the route selected to a presentation engine 420. The presentation engine 420 can, for example, communicate with a map system 440. In some implementations, the map system 440 can be provided, for example, by a navigation service (e.g., navigation service 230 of FIG. 2). In other implementations, the map system 440 can be provided by a map store residing on the mobile device (e.g., mobile device 100 of FIG. 1). The presentation engine 420 can use the map provided by the map system 440 to overlay the route information.

In one implementation, the route engine 410 can associate a reference with each of the routes generated. In another implementation, the route engine 410 can associate a reference with each route determined by tracking the mobile device 100. The reference can, for example, include one or more parameters associated with the route. The parameters can be associated with the names of the starting location 460 and ending location 462. The parameters can also be associated with user specified parameters associated with the route. The route engine 410 can, for example, save the route under the reference in the mobile device 100. The mobile device 100 can, for example, at any time, retrieve the saved route using the reference in response to a user input.

For example, suppose the starting location 460 of the route was indicated at the grocery store. Suppose also that the ending location 462 is the grocery store. The route can be saved with the reference “home to grocery,” or if the route was a scenic route, the route can be saved with the reference “scenic route.” In one implementation, the same route can be associated with one or more reference names. Therefore, the route in the above example can be associated with the reference “home to grocery,” as well as “scenic route.”

In another example, suppose an address of the user's house is indicated as the starting location 460 and the address of a friend's house is indicated as the ending location 462. The route engine 410 can generate a route from the user's house to the friend's house and display it for the user. A reference can be associated with this route and the route can be retrieved at a later time using the reference.

In one implementation, the mobile device 100 can be used in conjunction with an on-board navigation system for a vehicle. The mobile device 100 can provide route information to a user of the navigation system.

In one implementation, any route generated by the route engine 410 can be edited by an editor engine 430. A route can, for example, be edited by an editor engine 430 if it was created by tracking the mobile device 100 as described above. A route can also be edited if created by the route engine 410 by receiving a starting location 460 and an ending location 462 and the route engine 410 generating the route. In other implementations, any route previously created or saved by the route engine 410 or received from a peer through the mobile device 100, e.g., an SMS message describing the route, can be edited.

For example, a saved route can be retrieved by indicating the reference of the route. The route engine 410 can retrieve the saved route using the reference input by the user. While navigating according to the route guidelines, the mobile device 100 can receive an indication to edit the route. For example, a different road can be selected than the current road indicated on the route, or a different ending location 462 can be selected other than the one indicated on the route. Upon receipt of an edit, the editor engine 430 can track the position of the route to the ending location 462. In one implementation, the route engine 410 can associate the same reference with the edited route. In other implementations, the route engine 410 can, for example, associate the new route with a second reference. In one implementation, upon receipt of an edit location indicator, the editor engine 430 can track the position of the route to the ending location 462.

For example, suppose a route referenced as “back roads home from work” is selected. The mobile device 100 can retrieve the route using the reference “back roads home from work” and display the route for the user. An alternate road can be selected than the one indicated on the retrieved route at a certain point during the route. The mobile device 100 can receive an indication that the route “back roads home from work” is to be edited. The editor engine 430 can therefore start tracking the changes in the route from the point in time of receipt of the edit indication. At the ending location 462, the mobile device 100 can receive an indication that the ending location 462 has been reached. The route engine 410 save the edited route as “back roads home from work” and save this new route information. The route engine 410 can also select a new reference for the edited route, e.g., “back roads home from work not using highway.”

In one implementation, the route engine 410 can retrieve real time traffic information on the mobile device 100 as described above. The traffic information 464 can, for example, be related to a universe of area roads can be communicated to one or more mobile devices (e.g., mobile devices 100 of FIG. 1), and the route engine 410 can parse the signal to obtain traffic information 464 for route guidelines.

In one implementation, the current route can be edited based on the traffic information 464. The mobile device 100 can receive an edit location indicator and the route can be edited based on the traffic information 464. Editing the route can, for example, include receiving input of a different road than the current one displayed on the mobile device 100. For example, suppose a saved route is retrieved by the mobile device 100 by receiving an indication of a reference route A. The route includes directions from point A to point B. While navigating from point A to B according to “Route A,” the mobile device 100 receives traffic information 464 indicating heavy traffic where “Route A” indicates the next turn should occur. The mobile device 100 can then edit “Route A” by receiving an input of an edit location indicator. An alternative road can be selected from the current location. At any time, an indication can be received on the mobile device 100 to start tracking “Route A” from the current location. The editor engine 430 can track the mobile device 100 from the new location to the ending location 462. The route engine 410 can associate a new reference with the edited route, e.g., “alternative Route A,” or associate the same reference “Route A” with the edited route.

In some implementations, if a route is retrieved by a reference, the routing instructions 372 can continue to analyze a current route to monitor for changing conditions. For example, an accident between the start of navigation of a route and the end of navigation of the route might change the analysis associated with recommending the current route. In such situations, the routing instructions 372 using the route engine 410 can calculate alternative routes. In some implementations, the routing instructions 372 can automatically communicate a new route through the presentation engine 420. Such automatic rerouting can be provided with notification of the change or without notification of the change. In other implementations, the routing instructions 372 can present the estimated navigation times associated with alternative routes through the presentation engine 420. An alternative route can be selected based upon the estimated navigation times. The selection, in various implementations, can be indicated by selecting a route using an I/O device (e.g., touch screen 346 of FIG. 3), or by navigating one of the alternative routes, among others. Once the route changes, a new reference can be associated with the route. In other implementations, the same reference can be associated with the edited route.

In one implementation, the route engine 410 can learn to use a specific route when determining a route from a starting to an ending location. The route engine 410 can, for example, analyze all previous routes generated and navigated, and determine that one particular route is often used. In another example, the route engine 410 can keep a log entry every time a user edits a route and determine whether the route is edited to use a particular road. The route engine 410 can use this particular road the next time the route is generated.

FIG. 5 is a block diagram of an example mobile device using a route reference. The mobile device 100 can receive a map representation 500 from a navigation service (e.g., navigation service 230 of FIG. 2) of a reference 502. The map representation 500 can, for example, include route from a starting location 460 to an ending location 462.

FIG. 6 is a flow diagram of an example process 600 for generating a route. The process 600 can, for example, be implemented in the mobile device 100 of FIG. 1.

At stage 602 a user input is received on a mobile device specifying a starting location 460. The user input can, for example, be received by a mobile device (e.g., mobile device 100 of FIG. 1) in conjunction with sensor processing instructions (e.g., sensor processing instructions 358 of FIG. 3) and GPS/Navigation instructions (e.g., GPS/Navigation instructions 368 of FIG. 1) operating in conjunction with a wireless communication (324 of FIG. 3). The starting location 460 can be input manually by a user or be automatically determined by a positioning system (e.g., the positioning system 318).

At stage 604, a position of the mobile device is tracked from the starting location 460 in response to the user input. The position of the mobile device can, for example, be tracked by a positioning system (e.g., the positioning system 318 of FIG. 3) in conjunction GPS/Navigation instructions (e.g., GPS/Navigation instructions 368 of FIG. 3).

At stage 606 a user input is received on the mobile device specifying an ending location 462. The user input can, for example, be received by a mobile device (e.g., mobile device 100 of FIG. 1) in conjunction with sensor processing instructions 358 and GPS/Navigation instructions (e.g., GPS/Navigation instructions 368 of FIG. 3). The ending location 462 can be input manually by a user or be automatically determined by a positioning system (e.g., the positioning system 318).

At stage 608 a route is generated from the tracking of the mobile device from the starting location 460 to the ending location 462. Alternatively, the route can be generated without tracking that is based on a request to progress from a starting location to a destination without movement (e.g., prior to commencing the travel). The route can, for example, be generated by a route engine (e.g., route engine 410 of FIG. 4) in conjunction with GPS/Navigation instructions (e.g., GPS/Navigation instructions 368 of FIG. 3). The route can include directions from the starting location 460 to the ending location 462.

At stage 610 a first reference is associated with the route, wherein the route is retrievable by a selection of the first reference. The first reference can, for example, be associated with the route by a route engine (e.g., route engine 410 of FIG. 4) in conjunction with GPS/Navigation instructions (e.g., GPS/Navigation instructions 368 of FIG. 3).

FIG. 7 is an example process for associating a reference with a travel route. The process 700 can, for example, be implemented in the mobile device 100 of FIG. 1.

At stage 702 an input is received specifying a first location. The input can, for example, be received by a wireless device (e.g., mobile device 100 of FIG. 1) in conjunction with sensor processing instructions (e.g., sensor processing instructions 358) and GPS/Navigation instructions (e.g., GPS/Navigation instructions 368 of FIG. 3). The first location can correspond to a first geographic location.

At stage 704 input is received specifying a second location. The input can, for example, be received by a mobile device (e.g., mobile device 100 of FIG. 1) in conjunction with sensor processing instructions (e.g., sensor processing instructions 358) and GPS/Navigation instructions (e.g., GPS/Navigation instructions 368 of FIG. 3). The second location can correspond to a second geographic location.

At stage 706 a travel route is computed between the first and second geographic locations. The travel route can, for example, be computed by route engine (e.g., route engine 410 of FIG. 4) in conjunction with GPS/Navigation instructions (e.g., GPS/Navigation instructions 368 of FIG. 3).

At stage 708 an input is received indicating an edit. The input can, for example, be received by a wireless device (e.g., mobile device 100 of FIG. 1) in conjunction with sensor processing instructions (e.g., sensor processing instructions 358) and GPS/Navigation instructions (e.g., GPS/Navigation).

At stage 710 the travel route is edited on a wireless in accordance with the edit. The travel route can, for example, be edited on a wireless device (e.g., mobile device 100 of FIG. 1) in conjunction with GPS/Navigation instructions (e.g., GPS/Navigation).

FIG. 8 is an example process for editing a route. The process 800 can, for example, be implemented in the mobile device 100 of FIG. 1.

At stage 802 a user input is received specifying a first reference. The input can, for example, be received by a wireless device (e.g., mobile device 100 of FIG. 1) in conjunction with sensor processing instructions (e.g., sensor processing instructions 358) and GPS/Navigation instructions (e.g., GPS/Navigation).

At stage 804 a route is displayed on a wireless device. The route can, for example, be displayed on a wireless device (e.g., mobile device 100 of FIG. 1) in conjunction with sensor processing instructions (e.g., sensor processing instructions 358) and GPS/Navigation instructions (e.g., GPS/Navigation).

At stage 806 a user input is received specifying an edit. The input can, for example, be received by a wireless device (e.g., mobile device 100 of FIG. 1) in conjunction with sensor processing instructions (e.g., sensor processing instructions 358) and GPS/Navigation instructions (e.g., GPS/Navigation).

At stage 808 the route is edited by tracking the position of the wireless device to the ending location. The route can, for example, be edited by an editor engine (e.g., editor engine 430) in conjunction with GPS/Navigation instructions (e.g., GPS/Navigation).
